Dynamic Spectrum Arbitration for Wireless Handin
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing demand for radio frequency spectrum due to the rise in wireless communication devices leads to issues like dropped calls and slow internet access, especially during emergencies, as commercial cellular networks become overwhelmed, while underutilized RF spectrum in emergency service bands remains unused.
Innovation Solution
Dynamic spectrum arbitrage methods that dynamically allocate underutilized RF spectrum from one network to another, using a dynamic spectrum controller to identify eligible devices, determine signal strengths, and initiate handover processes to optimize resource usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If more wireless devices access commercial cellular networks, then network coverage and service availability improve, but network congestion increases causing dropped calls and slow internet access
Solution Approach 1:
The patent introduces an intermediary system (spectrum arbitration system) that mediates between commercial cellular networks and emergency service networks. This system dynamically allocates underutilized emergency service spectrum resources to commercial networks during congestion, acting as a mediator that resolves the contradiction between maintaining network coverage and preventing network overload.
Solution Approach 2:
The patent implements dynamic spectrum allocation where emergency service spectrum bands are allocated to commercial networks on-demand based on real-time network conditions. The system continuously monitors network load and dynamically switches spectrum usage between emergency services and commercial services, transforming static spectrum allocation into a dynamic resource sharing mechanism.
2Reliability
If emergency service RF spectrum bands are continuously allocated, then emergency communication reliability improves, but spectrum utilization efficiency deteriorates when not in use
Solution Approach 1:
The patent makes emergency service spectrum allocation dynamic rather than static. The spectrum is allocated to emergency services when needed and released for commercial use when not needed, optimizing both reliability and efficiency. The system monitors emergency service usage and automatically adjusts spectrum allocation in real-time.
Solution Approach 2:
The patent changes the parameter of spectrum allocation from fixed to variable. By implementing on-demand allocation based on actual emergency service needs, the system transforms the spectrum resource from a permanently reserved state to a flexibly allocated state, improving overall utilization efficiency while maintaining emergency reliability.
3Loss of energy
If dynamic spectrum reallocation is implemented, then spectrum utilization efficiency improves, but system complexity increases
Solution Approach 1:
The patent introduces a dedicated intermediary system (spectrum arbitration system) that handles the complexity of dynamic spectrum management. This specialized mediator coordinates between emergency service networks and commercial networks, managing spectrum allocation decisions and reducing the complexity burden on individual network operators.
Solution Approach 2:
The patent implements automated spectrum allocation mechanisms where the system self-manages spectrum reallocation based on predefined criteria and real-time monitoring. The automated decision-making processes and self-service capabilities reduce manual intervention requirements and simplify operational complexity despite the dynamic nature of spectrum management.
Data Source
AI summary
A dynamic spectrum arbitrage (DSA) system includes a dynamic spectrum policy controller (DPC) and a dynamic spectrum controller (DSC) that together dynamically manage the allocation and use of resources across different networks. The DSC component may be configured to receive notice that an eNodeB is congested, identify a geographic boundary area for a bid serviced by the congested eNodeB, generate a list of eligible active wireless devices that are inside the geographic boundary area, determine an available resource of target a eNodeB that services the identified geographic boundary area, select for handin to the target eNodeB wireless devices from the received list of eligible active devices, and send a handin initiate communication message to the target eNodeB servicing the wireless devices that are selected for handin.
